This is an updated version of a wallpaper that I made a long time ago. Someone named Mib emailed me a link to his improved version a while back, but I was having server probs at the time and lost the email. (So that's why I didn't email you back, Mib.) I've implemented his two ideas -- adding the RMS-compliant GNU prefix bisected with the flagpole and using И instead of N -- in the re-done versions, and have released the SVG source code.
